Warranty Disclaimer Addendum

Overview

A Warranty Disclaimer Addendum is an attachment to a Bill of Sale, Purchase Agreement, Rental Agreement, or Item Condition Report. It reinforces that the item is being transferred without warranties, and that the buyer or user accepts the item “as‑is.” This addendum provides an extra layer of protection by making the disclaimer a formal part of the contract.

Use this addendum when you need to:

  • Add a warranty disclaimer to an existing agreement
  • Clarify that no warranties apply to the sale or rental
  • Strengthen liability protection for used items, vehicles, trailers, equipment, or digital products
  • Ensure the buyer acknowledges the “as‑is” condition in writing

This addendum allows you to:

  • Attach a clear “as‑is” disclaimer to any contract
  • Disclaim express and implied warranties
  • Limit liability for defects, performance issues, or inaccuracies
